[accompanying drawing explanation]
Fig. 1 is the structural representation of the repeater that the utility model provides;
Fig. 2 is the structural representation of the monitoring module of repeater shown in Fig. 1.
[embodiment]
With reference to figure 1, the utility model one embodiment provides a kind of repeater 200, comprises monitoring module 210 and some radio-frequency modules 220, and some radio-frequency modules 220 are connected to monitoring module 210 by RS485 bus.Radio-frequency module 220 has self detecting function, radio-frequency module 220 comprises radio circuit (not shown), MCU (not shown), RS485 serial line interface (not shown), MCU connects radio circuit, MCU adopts 51 single-chip microcomputers, and the MCU that RS485 serial line interface is radio-frequency module 220 and monitoring module 210 interactive information provide communication interface.
With reference to figure 2, monitoring module 210 comprises central processing unit 211, RJ45 interface 212, RS232 serial line interface 213, RS485 interface 214, memory cell 215, data card unit 216 and power module 217.RJ45 interface, RS232 serial line interface 213, RS485 interface 214, memory cell 215 and data card unit 216 communicate to connect with central processing unit 211 respectively, and power module 217 is connected to central processing unit 211 for power supply.Central processing unit 211 adopts high pass one chip solution, uses linux operating system, realizes the monitoring function to repeater and the covering of wifi wireless network.In the present embodiment, data card unit 216 comprises 3G/4G data card, supports 3G/4G wireless traffic, can provide the function that dials up on the telephone, SMS for monitoring module 210.Dialled up on the telephone by 3G/4G data card, start auto dialing, after dial-up success, converts thereof into Wifi network signal, for terminal equipment provides wireless networking capabilities.In addition, because data card unit 216 adopts the MINI PCI-E interface of standard, USB2.0 communication interface, MINI PCI-E interface has powerful extended capability, can easily 3G/4G data card be replaced with in WCDMA data card, EVDO data card, TD-LTE data card, FDLTE data card one of at least.RS232 interface 213 connects monitoring module and terminal PC, realizes local man-machine interaction.Also can pass through 3G/4G data card 216, adopt short message mode or number biography mode, realize remote human-machine mutual.Memory cell 215 comprises SRAM, DDR, SPI FLASHROM, runs for storage code, back-up system program and stores the information of monitoring parameter and the information of wireless terminal user.RJ45 interface 214, for the connection of ethernet interface circuit and Ethernet switching chip, realizes Ethernet exchanging function.Power module 217 is responsible for whole monitoring module 210 and powers.
For the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection range of the present utility model.Therefore, the protection range of the utility model patent should be as the criterion with claims.
